AdMob in Android

Android AdMob Banner Ads in Recyclerview - Androidchunk

Hi Android developer!

App prerequisites

Make sure that your app's build file uses the following values:

Minimum SDK version of 19 or higher
Compile SDK version of 33 or higher

Add the dependencies for the Google Mobile Ads SDK to your module's app-level Gradle file, normally app/build.gradle:


dependencies {
  implementation ("com.google.android.gms:play-services-ads:22.6.0")
}

Add your AdMob app ID, as identified in the AdMob web interface, to your app's AndroidManifest.xml file.

To do so, add a <meta-data> tag with android:name="com.google.android.gms.ads.APPLICATION_ID".

You can find your app ID in the AdMob web interface. For android:value, insert your own AdMob app ID, surrounded by quotation marks.


<manifest>
  <application>
<!-- Below this is test id replace for value tag-->
<!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>
  </application>
</manifest>

In a real app, replace the sample app ID with your actual AdMob app ID. You can use the sample ID if you're just experimenting with the SDK in a Hello World app.

Also, note that failure to add the <meta-data> tag exactly as shown results in a crash with the message:


The Google Mobile Ads SDK was initialized incorrectly.

(Optional) Declare AD_ID permission for previous versions to work with Android 13.

Initialize the Google Mobile Ads SDK

Before loading ads, have your app initialize the Google Mobile Ads SDK by calling MobileAds.initialize()

which initializes the SDK and calls back a completion listener once initialization is complete, or after a 30-second timeout. This needs to be done only once, ideally at app launch.

Here's an example of how to call the initialize() method in an Activity:

Example MainActivity (excerpt)


import com.google.android.gms.ads.MobileAds

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
				
				// To Intialize AdMob
        MobileAds.initialize(this) {}
    }
}

Select an ad format

The Google Mobile Ads SDK is now imported and you're ready to implement an ad. AdMob offers a number of different ad formats, so you can choose the one that best fits your app's user experience.

Banner

Rectangular ads that appear at the top or bottom of the device screen.

Banner ads stay on screen while users are interacting with the app, and can refresh automatically after a certain period of time. If you're new to mobile advertising, they're a great place to start.
